26: The Mongol In Our Midst was a 1920s pseudoscience book claiming that Down’s Syndrome (sometimes called mongolism because affected babies look kind of Asian if you’re racist and have a vivid imagination) was literally caused by relic Asian genes that Europeans got from Mongol hordes raping their ancestors. Seems to have been taken somewhat seriously at the time and was reviewed in JAMA and Nature, though I can’t access the reviews to see how critical they were.

Second, isn’t it preposterous and against common sense to compare sub-Saharan Africans to the intellectually disabled? You can talk to a Malawian person, and talk to a person with Down’s Syndrome, and the former is obviously much brighter and more functional than the latter. Doesn’t that mean that the estimates have to be wrong?
Kirkegaard explains that when we think of intellectually disabled people we’ve met, we’re usually thinking of people with some specific syndrome - often Down’s Syndrome, fetal alcohol syndrome, or severe autism. These people have abnormally low IQ. But their syndromes also cause motor deficits, executive function deficits, emotional processing deficits, and many other forms of deficit.
For example, people with Down’s Syndrome may have trouble speaking, or speak abnormally. But this is primarily because Down Syndrome affects hearing (through ear structure abnormalities) and speech production (through tongue/mouth/chest abnormalities). The cognitive issues are only responsible for a small part of the deficit.
